Since comet Hartley 2 -- the target of Deep Impact's November 4 flyby -- is near its perihelion, it's no surprise that it's an active comet with lots of outbursts.
The week is finally here: Deep Impact flies past Hartley 2, the smallest comet yet to be visited by a spacecraft, on Thursday, November 4 at 13:50 UTC.
